Sure; there are solar ovens that do precisely that.One design is to simply cover an enclosed area with glass. The heat gets "trapped" inside (the glass is transparent for visible light, but not to infrared radiation); and the temperature inside gets hot enough to do baking.
Another design is to concentrate light with a parabolic mirror - concentrating it on a spot where the pot is suspended.

Why visible light can't cook food like microwaves and Doesn't the visible light have higher energy than microwaves?
Visible light does have higher energy than microwaves, but it is not efficient at heating food because it is mostly absorbed by the food's surface and then reflected or transmitted without deep penetration. Microwaves, on the other hand, are designed to interact with water molecules in the food, causing them to vibrate and generate heat through friction. This allows microwaves to cook food more effectively and efficiently.
Are microwaves a form of visible light?
No, microwaves are not a form of visible light. They fall within the electromagnetic spectrum at lower frequencies than visible light. Microwaves are used in appliances like microwave ovens for cooking food.
What do the visible colars of light represent?
The frequency range of visible light.
Are X-rays visible light?
No, x-rays are not visible light.
What has more energy a visible light or infrared light?
Visible light has more energy than infrared light. This is because visible light has shorter wavelengths and higher frequencies compared to infrared light.
Does a microwave use light energy?
Yes, a microwave uses electromagnetic radiation in the form of microwaves to generate heat and cook food. Microwaves are a type of light energy on the electromagnetic spectrum, with a wavelength longer than visible light.
What can you do with just a match?
You can light up a stove and cook some food. If you are ever stuck alone in the woods that match can provide you with light, warmth, and it can cook food.
Do any microwaves use light to help cook?
Microwaves use radiation to cook food and radiation is a form of light. They do not use actual light bulbs to cook though.

What is infared light?
It's a wavelength of light which is outside the visual spectrum.
What are some reasons why you need fire?
Warmth, to cook food, and light
Is light energy used in a microwave oven?
Yes, light energy is used in a microwave oven to generate microwaves that heat and cook food. However, the light energy in a microwave oven is not visible to the human eye.
How did poor girls cook food without a cooker?
light a small fire and put a pot over it. then put soups and other foods into it. It would cook and there you have it, nice hot food!!
What one is more energetic microwaves radio waves or visible waves?
Visible light has a shorter wavelength, and therefore a higher energy content than microwaves. You may wonder how this is possible, when microwaves heat up your food so effectively, and visible light doesn't. That's because a microwave oven produces microwaves that are tuned to the exact resonant frequency of the water molecule. Otherwise, the microwaves would heat your food even less than an ordinary light bulb would. =============================================================================== Your answer is only partially correct. The difference in frequency (visible light is much higher) makes the energy content of visible light 30,000 to 50,000 times greater than that of microwave radiation. Where you are incorrect is saying that the microwaves have "the exact same resonant frequency of the water molecule". Actually, the resonant frequency of water at room temperature is about 22 gigahertz (GHz), while the frequency of the waves in a microwave oven is 2.45 GHz, almost an order of magnitude lower. Further, as the water gets hotter, its resonant frequency increases and so couple the microwave energy less and less; so warm and hot water heat more slowly that cold water. The major reason visible light isn't used to cook food is that its penetration depth into the food (directly related to its wavelength) is so small that it can only heat the surface - it has virtually no penetration into the food. Visible light has been used, in the form of a halogen bulb in some microwave ovens so the microwave heat or cook the bulk of meat, while the visible light browns and even crisps the surface.
Are microwaves a form of visible light?
No, microwaves are not a form of visible light. They fall within the electromagnetic spectrum at lower frequencies than visible light. Microwaves are used in appliances like microwave ovens for cooking food.
Does osmosis cause food coloring to change the color of water?
It absorbs different wavelengths of visible light
What kind of light is normal light that you use?
The answer is visible light. Visible light is light that can be seen with a naked eye
